Y4-73 boiler centrifugal fan(D type)

Type G4-73 and Y4-73 boiler fans are used for a fan system of2 ~670T/h steam boilers in a thermal power plant. Also, the G4-73 can be used for ventilation of mine in a general ventilation, Ventilator conveying medium for air, the highest temperature shall not exceed 80 and induced draft fan conveying medium for flue gas, the highest temperature shall not exceed 250 . Moreover, G4-73isequipped with Type A Reloadable Motor. The type of general ventilation motors are made according to an E- class standard and the type of High-temperaturemotoris made of high-temperature resistant materi als. For heat dissipation,acooling wind wheel is added to the lengthened shaft between the impeller and the motor housing, which can effectively block the heat transmitted by the impeller,The structure of G4-73 is simple.
